JOHN KIRK, OF CINCINNATI, OHIO.

SAW-TABLE GAG E.

SPECIFICATION forming part of Letters Patent No. 267,001, dated November'7, 1882,

Application filed July 21, 1882.

To all whom it may concern Be it known that I, JOHN KIRK, of Cincinnati,in the county of Hamilton and State of Ohio, have invented a new anduseful Improvement in Saw-Table Gages,\vhicl1 improvement is fully setforth in the following specification and accompanying drawings, inwhich- Figure 1. is a top or plan View of asaw-table equipped with myimproved gage. Fig. 2 is a frontelevation of same. Fig. 3 is an enlargedfront view, partly in section, of the gage-board, guide-pin, and roller;Fig. 4, atop view of the various rollers, and Fig. 5 an enlarged topview of the gage-board.

The object of my invention is to provide an accurate adjustable gage forsaw-tables; and it consists in a plate secured to the saw-table, havinga series of regular perforations, which are adapted to receive pinshaving rollers or cylinders of various diameters, whereby the distancesto or from the saw-blade maybe regulated in a regular and systematicmanner, all of which will now be set forth in detail.

Referring to the accompanying drawings, A represents the saw-table; B,the saw, and O the sliding or reciprocating table upon which thematerial to bccut. is placed.

On the forward side of the table, and parallel with the saw-mandrel, isa metallic plate, D, of suitable width and thickness, sunk into thetable so as to be flush with the upper surface. The plate is located onthe right side of the saw, as shown in Fig. 1, so that its inner endwill be exactly on a line with the out of the saw. The plate D has fourrows of perforations, E F G H, of even size, adapted to receive a pin orpins, I, having a head, J, as shown in Fig. 3.

K represents a roller or cylinder, through which the pin I also passes.A set of rollers, preferably eight in number, are designed foreachtable. Theserollersincreasesuccessively in size diametrically by onethirty-second of an inch radius, the object of which will now beexplained in connection with the gage-plate.

As shown more clearly in Fig. 5, the hole numbered 1 in the first row,E, is so located that when the center pin, I, is placed therein and thesmallest roller used thereon the distance between the saw-line (shown byw) and the said No model.)

roller will be one inch. Using this distance as a guide, the successiveholes 2 3 4, 850., in row E are placed an inch apart from center tocenter, so that if the same roller should be. used in the successiveholes the distances between the saw and roller would be aninch greaterat and the first hole in the fourth row, H, so that the distance betweenthe roller and the saw will be one and three-fourths inch. Thus theuniform gradations in the plate indicate spaces equal to one-fourth ofan inch in this instance, although itis obvious that they may be anyother distance apart. The only rule to be observed is that the distancesbetween the holes shall be uniform. It will be readily seen that ifrollers of varying sizes, as shown in Fig. 4, are placed upon a centerpin located in one of the holes, any intermediate thirty-second of aninch may be measured between the sawand the roller. Thus, in use, if theoperator desires to cut material of any length which is measured byinches, the center pin is placed in the row E; if a quarter of an inchmoreis desired, it is removed to row F; if a half-inch more is desired,it is moved to row G, and if three-fourths is desired, row H. To cutlengths which are intermediate between the quarterinch measures, thevarying rollers K are employed, and since they are graduated in size, as

stated, by the thirty-second part of an inch, it is obvious that anydesired length of material can be cut. The first row of holes, E, havepreferably the successive numbers 1 2 3 4, &c., and the spoolsor rollersmay also be suitably marked, so they can be readily distinguished onefrom the other.

In operation, the board L to be cut is placed on the table and drawnforward so that the 9 board will clear the saw. The end of the board isfirst cut off square, the table again drawn back, and the board movedover to the right until the end touches the roller, when the table ismoved toward the saw, which cuts off adapted to be placed in saidholesand a roller placed thereon, and with the reciprocating table and saw,substantially as and for the pur pose herein shown.

2. A gage for saw-tables, composed of a centerpin adapted to be placedin suitable holes in the plate or table, carrying rollers or spools 20which regularly increase in size with respect to each other, incombination with the reciprocating table and with the saw, substantiallyas and for the purpose herein set forth.

3. The plate D, secured permanently to the saw-table, and having theperforations, as shown, at regular intervals and alternating,incombination with the removable center pin, I, having the rollers K, ofvarying sizes, and with. the reciprocating table and saw, substantiallyas and for the purpose herein shown.

In testimony that I claim the foregoing I have hereunto set my hand,this 18th day of July, 1882, in the presence of witnesses.

JOHN KIRK.
